Segmentation fault

[easydowork]

I make a simple demo , like this

#include <phpcpp.h>
#include
void myFunction()
{
Php::out << "hello world" << std::endl;
}
extern "C" {
PHPCPP_EXPORT void *get_module() {
static Php::Extension extension("my_extension", "1.0");
extension.add("myFunction");
return extension;
}
}

but ,when I test this extension , the CLI mode echo :

"hello world
Segmentation fault"

It seems you have few errors in your files.

your file:

#include <phpcpp.h>
#include          /* MISSING INCLUDE FILE */
void myFunction()
{
Php::out << "hello world" << std::endl;
}
extern "C" {
PHPCPP_EXPORT void *get_module() {
static Php::Extension extension("my_extension", "1.0");
extension.add("myFunction"); /* MISSING FUNCTION TYPE <myFunction> */
return extension; /* MISSING METHOD  module() LESS IMPORTANT WORKS WITHOUT*/
}
}

simpledemo.cpp after correction + change name of extension from my_extension to simpledemo

#include <phpcpp.h>
#include <iostream>

void myFunction()
{
	Php::out << "hello world" << std::endl;
}

extern "C" {
	PHPCPP_EXPORT void *get_module() {
		static Php::Extension extension("simpledemo", "1.0");
		extension.add<myFunction>("myFunction");
		return extension.module();
	}
}

simpledemo.php

#!/usr/bin/env php
<?php
declare(strict_types=1);

$extname = 'simpledemo';
if ( ! extension_loaded($extname) ) {
    if ( false === @dl($extname.'.so') )
        die('Unable to load extension '.$extname.PHP_EOL);
}
    
echo myFunction() . "\n";

All works fine.

Examples files provided with PHPCPP are good templates for your usage but copy or modify them carefully.
